Carbon monoxide bound to iron or copper in substrate-reduced mitochondrial cytochrome c oxidase (ferrocytochrome c:oxygen oxidoreductase, EC 1.9.3.1) from beef heart has been used to explore the structural interaction of the a3 heme-copper pocket at 15 K and 80 K in the dark and in the presence of visible light. The vibrational absorptions of CO measured by a Fourier transform infrared interfer...

In order to investigate the functional effects of mitral valve surgery, echocardiograms showing left ventricular dimension were recorded and digitised in 14 normal subjects and 129 patients after mitral valve surgery. Measurements were made of peak rate of increase of dimension (dD/dt) and duration of rapid filling, studies on left ventriculograms in 36 patients having shown close correlation b...

Soil organic carbon (SOC) dynamics in agro-ecosystem is largely influenced by cropping. However, quantifying the contributions of various crops has been lacking. Here we employed a stable isotopic approach to evaluate the contributions of wheat and maize residues to SOC at three long-term experimental sites in north China. Soil samples were collected from 0-20, 20-40, 40-60, 60-80 and 80-100 cm...

OBJECTIVE To systematically evaluate the noise generated by toys targeted for children and to compare the results over the course of 4 consecutive holiday shopping seasons. STUDY DESIGN Experimental study. SETTING Academic medical center. SUBJECTS AND METHODS During 2008-2011, more than 200 toys marketed for children older than 6 months were screened for loudness. The toys with sound outp...

This paper addresses an important problem in Example-Based Machine Translation (EBMT), namely how to measure similarity between a sentence fragment and a set of stored examples. A new method is proposed that measures similarity according to both surface structure and content. A second contribution is the use of clustering to make retrieval of the best matching example from the database more eec...

The fission cross sections of 247Cm, 254Es, and 250Cf are measured with the Rensselaer intense neutron spectrometer from 0.1 eV to 80 keV. The cross sections are normalized to the 235U ENDF / BV broadened cross section. Fission areas and resonance widths are determined for lowenergy resonances in 247Cm. The 254Esand 250Cffission cross sections are the only reported measurements for these isotop...

Present-on-admission modifiers for International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) diagnosis codes are rapidly becoming a standard coding requirement. Inaccurate coding of these modifiers can distort analyses of risk-adjusted outcomes and determinations of hospital reimbursement. A set of 12 screens for the plausibility of present-on-admission designat...

The treatment methods available for large primary hepatocellular carcinomas (diameter >5 cm) are inadequate. Here, we report the successful management of 80 cases of large hepatocellular carcinoma, using a combination of custom-designed permanent interstitial iodine-125 seed brachytherapy and palliative surgery. Patients were enrolled in the study between 2011 and 2014. All patients underwent s...

Albendazole (ABZ) presystemic clearance was studied in rat by perfusion of a 25 microM ABZ solution in isolated intestinal loops. Significant secretion of the active metabolite, ABZSO, into the lumen was observed. The metabolite was also present in mesenteric blood. After 30 min of intestinal perfusion, 64% of the ABZ dose had disappeared from lumen. The total amount of ABZSO measured was 0.341...
